Why flat roofs need more attention
Flat and low-slope roofs (pitch less than 2:12) don't shed water as readily as steep-slope roofs. Water pools in low spots, debris accumulates without sliding off, and the membrane is directly exposed to foot traffic from HVAC technicians, window washers, and maintenance crews.
With a consistent maintenance program, flat roofs meet or exceed their expected lifespan. Neglect, however, is punishing, a small drain blockage leads to ponding, which leads to membrane degradation, which leads to leaks, which leads to saturated insulation and a six-figure replacement.
